A flight evaluation of a gated LLLTV light-level television) system for ,SAR (search and rescue) was conducted 4 the Naval Missile Center, Point Mugu. California. The primary purpose of this program was to ascertain the effectiveness of the LLLTV system in acquiring targets (radiating targets, cooperative or noncooperative targets) at night on the ocean surface with the system operating in the passive or active (laser illumination of the target) modes. The second purpose was to compare standard light-signalling devices with a chemiluminescent device (Chemlite) as targets for LLLTV; and to compare their visual (optically unaided) acquisition distances. The third purpose was to de-termine whether or not the standard Navy sea dye, marker, excited by a nitrogen-gas pulsed laser,. would provide a visible light source with sufficient illumination to (1) serve as a visual reference for helicopter night hover, (2) enhance the bility of the searchers to locate a survivor, and (3) be readily acquired by LLLTV.
